Answer:
If x= 4 then f(x) = 4x -5 is 11.
Step-by-step explanation:
f(x) = 4x -5
We need to find the domain value that corresponds to the output f(x) = 11
In this question, we need to solve the expression for value of x such that the answer is 11.
if x= 3
f(3) = 4(3) -5
= 12 -5
= 7
Since we want the answer 11 so we cannot take x= 3
if x = 4
f(4) = 4(4)-5
= 16 - 5
= 11
So, if x= 4 then f(x) = 4x -5 is 11.

Here's the equation for one year:
0.06(6500) + 6500
But because it is 25 years:
25(0.06(6500)) + 6500
1.5(6500) + 6500
We can make it simpler:
2.5(6500)
The total amount is $16350

If one of our zeros is 4, then the factor is x-4. If the second zero is 5i, then the conjugate root theorem says there HAS to be a root that is -5i. So our 3 factors are (x-4)(x+5i)(x-5i). We will FOIL out these factors to get the polynomial. Let's start with the ones that contain the imaginary numbers. Doing that mutliplication we get x^2-25i^2. i^2 is equal to -1, so what that expression simplifies down to is
. Now we will multiply in that last factor of (x-4):
. FOILing out we have
. There you go!
